This is LTIessential in orderthat the disk may be effec-v tive in operation when achain or like means exert-ing no tension to hold the disk to its work isemployed, since it enables the disk to dig into the ground in operationunder its own weight. It will berapparent thatthis weight may be moreefficiently utilized by positioning the pivotal point of the vfront endof the stump-jump arm below the horizontal plane of the axis of thedisk, and the drawing shows such an arrangement. noticeable that thepivotal point of the stump`-jump arm is as low as may be to avoidrubbish, which is important.

vIn lieu of the chain 28,Y I may provide a metal rod or a powerfulspring, which,

upon retraction of the hand-lever 29 will enable sufficient downwardpressure to be exerted on the stump-jump arm such asfmay be necessary tomaintain the disk or. disks in hard ground being cultivated. It is notmy purpose, however, to provide. either the rod or the spring hereinreferred to unless the plow is to be specially'equipped for use in soilharderthan that usually'encountered,

and harder than that for which disk plows With respect to the metal rod,I may here Y state that this should only be usedy at a time when thecapability of the disk to ride overl an obstruction is not material. Aninstance of such use may be recited .in the digging of a trench in hardsoil. I have found in practice that this plow is capableV of such use bythe substitution of a 4stiff rod for the chain, or other iexibleconnection, the correlation of the axis `of the disk and the axis of thepivotal'movement of the disk-carrying arm substantially contributing tothe capability of the disk to turn vthe land, since said correlation issuch, as already stated, that the tendency is for the diskto dig itselfintothe ground. I may further here state that the rod is 4preferablyfurnished as a separate attach1n.e'nt,.when it is desired to provide aplow of simple, practicaland comparativelyA light draft constructionadaptable to turn soil for tillage purposes and to dig trenches or thelike. Y

n The plow has a seat 33 which may be of ordinary type and a foot-rest34 which is secured to the plow frame 2 is provided on its upper surfacewith end stops 35 of anglesection metal.

' The adjustment of thel land-wheels .7 transversely of the implement bythe means herein described provides for the yconversion of the implementfrom a single disk to a double disk plow or vice Versa., andfurthermore,

such adjustment relatively to the disk or disks controls the width offurrow. To adjustably support the rear end of the stumpjump arm,particularly when the plow is being used `in boggy soil, and to aid theadjustable hand-lever 29 in regulating the Inv fact, it isv -depth offurrow, askid 36 'is pivotally mounted upon a boltor pin 37 secured tothe bearing 13 of the stump-jump arm 12. This skid is constructed havinga foot-piece 38 adapted to ride upon, without cutting into,

the surface of the ground and thus limits the v cutting depth of thedisk or disks; The footvber 39 having a series `of adjustment holes I 40to receive a lockingstud 41-f-see Figure 2.

By removing the locking stud, the skid can be swung on the pivot bolt orpin 37 to elevate its foot-piece 3,8 to required height, when said skidis again locked in operative position by inserting thestud into aconvenient adjustment. Y

What I claim as Amy invention, and desire to secure by Letters'Patent isl.
